>Description:
Adding a default route (route add default x.x.x.x) introduces a very long
(over 2 min) delay for all network related functions (telnet, ftp, arp -a...).
I can ping and telnet to my local machine (either localhost or IP address)
BEFORE I put in a default route without any problems. I can also do the same
to anyone on my local segment.
AFTER I put in the default route, pings seem to work just fine, but the other
higher applications (telnet, ftp, etc...) lag for some time before connecting
to ANYTHING (hosts off of my segment, on my segment, or even to myself). I also
noticed that when a default route is in place, the ppp user process will pause
when launched. When I remove the default route, everything goes back to normal.
